Introduction
Terminology Analysis
| Term Classification | Core Indicators | Technical Characteristics |
|---|---|---|
| Basic Terminology for Zoning | AridityK=Em/P | FAO Penman-Monteith Model Calculation |
| Water-saving Irrigation Technology | Section 3.5.4 Sprinkler Pressure Requirements | Irrigation Equipment Standards for 30-50m Range |
| Drought-resistant Variety Selection | Soil Moisture Content≤12% | Yield Stability Increased by 25%-40% |
Comparison of zoning indicators
Take the semi-arid area (350-450mm) as an example. The area implements grass-field rotation and adopts ridge and furrow rainwater collection planting to increase rainfall utilization rate by 18%, and the organic matter content has increased by 0.3g/kg in three years.
| Region type | Precipitation (mm) | Planting ratio | Dryland farming technology |
|---|---|---|---|
| Arid area | <200 | Irrigation agriculture95%+ | Film mulching + drip irrigation |
| Semi-humid area | 550-650 | Rain-fed agriculture80% | Contour planting |
Implementation guidelines
Promote implementation in semi-arid areas with K values of 1.75-3.50:
- Give priority to drought-resistant varieties and grades Z65 series
- Rainwater collection system construction parameters: cellar capacity of 30m³/mu
- Implement GB/T50363-2018 water-saving irrigation standard requirements
